Comparison of Three Surgical Approaches for Lateral Sinus Floor Elevation
Sponsor: Istanbul Aydın University
Summary
This prospective comparative clinical study evaluates three surgical approaches used for lateral sinus floor elevation: the standard rotary technique, an epinephrine-soaked cotton roll-assisted technique, and a piezoelectric technique. The study compares intraoperative bleeding, surgical field visibility, procedural simplicity, operation time, and the occurrence of Schneiderian membrane perforation. It also examines whether patient- and anatomy-related factors, including smoking, residual bone height, sinus membrane thickness, and sinus septa, are associated with membrane perforation. The aim is to determine which factors contribute most strongly to surgical conditions and perforation risk during lateral sinus floor elevation.

Interventions
Conventional Rotary Lateral Sinus Floor Elevation
A lateral sinus window is created using a rotary round diamond bur. After removal of the bony window, the Schneiderian membrane is elevated using conventional manual sinus instruments. Membrane integrity is evaluated by direct visualization and the Valsalva maneuver. Subsequent grafting and implant-related procedures are performed according to the standardized study protocol.
Epinephrine-Soaked Cotton Roll
A lateral sinus window is created using a rotary round diamond bur. Following initial reflection of the Schneiderian membrane, a cottonoid soaked with one carpule of 4% articaine containing 1:100,000 epinephrine is placed over the exposed sinus membrane and bony window for 5 minutes to promote local hemostasis. After cottonoid removal, membrane elevation is continued using conventional manual sinus instruments. Subsequent procedures follow the standardized study protocol.
Piezoelectric Sinus Lift
The lateral sinus window is created using US2 and UL4 piezoelectric surgical tips. The Schneiderian membrane is subsequently elevated using UL2 and UL5 piezoelectric inserts, supplemented with conventional manual sinus instruments when necessary. Membrane integrity is evaluated by direct visualization and the Valsalva maneuver. Subsequent grafting and implant-related procedures are performed according to the standardized study protocol.
